Do I need to Calibrate the system?

Each plate comes calibrated and will be zeroed when plugged in, prior to scanning and if the software detects a value below 20N or above 50N at rest.

No! When each force plate is made, the strain gauges in the feet are initially calibrated to a standardized weight. Once this initial calibration is completed, the data is stored in the firmware of the hardware itself, allowing the software to tare or zero the plate when drift is detected.

You can learn more about the standardization settings here: How does Sparta standardize its data?

The force plate is tared/zeroed in three different cases:

  1. Prior to each assessment
  2. In the case that the software ever detects a value below -20N or above 50N at rest
  3. Each time the force plate is physically plugged in
